2023: Mail Server Migration

Migration from the Zimbra Mail solution to the Russian Tegu Enterprise was carried out.

During the project, a fault-tolerant cluster of two postal nodes was built. Thanks to the ability servers of Tegu to work with several directory services, employees "" Galex were able to place more than 2,500 users on the service and combine disparate mail. domains The client was asked to use, DBMS PostgreSQL which provides storage and backup of more than 1.5 TB of data and, in the event of an increase in users, is designed for a double increase.

Balancing mail flow through two providers together with the security settings of the Tegu mail solution gives the solution additional resilience in the current realities of DDoS and other infrastructure attacks.

As a result, the migration was carried out with the transfer of all user mail. The total downtime at all stages of the service implementation was less than 2 hours.
